Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
In the embodiment of the present application; for OTN (the Optical TransportNetwork of any two different manufacturers; optical transport network) equipment; if business mapping mode, multiplexing structure mode and protected mode homogeneous phase are simultaneously; then can based on OTUk (Optical Transform Unit k; optical conversion element k) interface; OTN equipment connection between described any two different manufacturers is carried out networking; the embodiment of the present application, achieves interconnecting between different manufacturers OTN equipment.
A kind of flow chart realizing a method embodiment of different manufacturers OTN equipment network that Fig. 1 provides for the embodiment of the present application, the method can comprise following step:
101: between the OTN equipment detecting any two different manufacturers, at least whether business mapping mode, multiplexing structure mode and protected mode be identical.
102: at least described business mapping mode, multiplexing structure mode and protected mode homogeneous phase simultaneously, determine the OTN equipment between described any two different manufacturers, can connect based on Optical Channel Transport Unit-k OTUk interface; Wherein, k=1,2,2e or 3.
103: based on described OTUk interface, by the OTN equipment connection between described any two different manufacturers, realize interconnecting.
OTN is based on wavelength-division multiplex technique, in the transport network of photosphere organization network, is follow-on Backbone Transport Network.
After different OTN equipment network, can realize interconnecting.Inevitably there will be the situation of the OTN equipment network of different manufacturers in actual applications; in prior art; the OTN equipment of different manufacturers normally carries out docking intercommunication based on business interface mode; but business interface is a kind of logic interfacing; business adopts the mode of segment transmissions to transmit, and protective capability and service transferring mode have certain limitation.
And in the embodiment of the present application; by detecting the OTN equipment with networking requirements of any two different manufacturers; if the business mapping mode of Liang Ge producer, multiplexing structure mode and protected mode etc. are identical; then these two OTN equipment both can connect based on OUTk interface; according to the transmission rate of the OTN device transmission type of service of Liang Ge producer; in the embodiment of the present application, OTUk interface can be OTU1, OTU2, OTU2e or OTU3 interface, and each OUTk interface supports different transmission rates.
ITU-T G.709 in define 3 kinds of different business mapping modes, comprise: AMP (AsynchronousMapping Procedure, asynchronous mapping code), BMP (Bit-synchronous Mapping Procedure, bit synchronous maps code) and GMP (Generic Mapping Procedure, general mapping code).
When carrying out business transmission, different business adopts different business mapping modes to map.
Only have the business mapping mode of two OTN equipment identical, just can realize business transmission, otherwise business maps unsuccessfully, business cannot OTN equipment connection between Liang Ge producer, therefore need the OTN device map mode of Liang Ge producer identical, connect based on OTUk interface, business transmission could be realized.Therefore, in order to realize interconnecting, the OTN equipment of different manufacturers needs the business board selecting identical services mapping mode.
Because different vendor is different with the OTN multiplexing structure selected during deisgn product in planning, and the implementation that corresponding international and domestic standard does not have clear and definite specification unique yet.For example ODUk (k=1/2/2e/3) (Optical channel Data Unit k, light path data cell k), producer A have selected directly multiplexing structure for ODU0-ODU2.Producer B then have selected the structure multiplexing step by step of ODU0-ODU1-ODU2, and producer A, because multiplexing structure is different then can not connect based on OTUk interface with producer B, so that avoid cannot correct demultiplexing, causes two OTN equipment cannot intercommunication.
Protected mode refers to and can configure two bang paths at OTN, and one is predominating path, and one is backup path, when predominating path breaks down, still can ensure business normal transmission by backup path.The protected mode that the embodiment of the present application relates to that is to say SNCP (SubNetwork ConnectionProtection, SNCP) mode.
Wherein, the SNCP protection based on ODUk defines three kinds of different protected modes, comprising: the ODUk SNCP (SNCP/I) utilizing Inherent monitoring; Utilize the ODUk SNCP (SNCP/N) of non-intervention supervision; Utilize the ODUk SNCP (SNCP/S) of sublayer monitors.The alarm conditions that the monitoring level of these three kinds of schemes and triggering are switched are distinguished to some extent; the tenability of each producer to SNCP/I, SNCP/N, SNCP/S tri-kinds of protected modes is not quite similar; the OTN equipment of the Liang Ge producer therefore only having protected mode identical can connect based on OTUk interface; realize OTN device intercommunicating; even if otherwise OTN equipment connects based on OTUk interface, OTN equipment also cannot intercommunication.
Therefore, in the embodiment of the present application, at least demand fulfillment business mapping mode is identical, multiplexing structure is identical and protected mode is identical for the OTN equipment of any two different manufacturers.
Certainly, in order to ensure that the OTN equipment of different manufacturers is based on after OUTk connection further, can interconnect, devices from different manufacturers inside realizes details and also can not be ignored.As for the numbering otherness of time slot interface, the design for internal hardware buffer memory tolerance limit, the tenability support of different cross grain (such as) etc. for the own design of specification part non-in standard, specific board matches.Therefore, after completing above-mentioned three steps, the inside can also noticing different manufacturers realizes details.
In order to ensure any two different manufacturers OTN equipment connection after; can realize interconnecting; the embodiment of the present application can also to interconnect test to OTN equipment; main to business transmission, protected mode, TCM (Tandem Connection Monitoring; Tandem Connection Monitor) and long-term behaviour etc. verify
Therefore as shown in Figure 2, based on described OTUk interface, by the OTN equipment connection between described any two different manufacturers, after realizing interconnecting, described method also comprises:
201: respectively to test that the OTN equipment between described any two different manufacturers is interconnected.
Wherein, test of interconnecting described at least comprises business transmission checking, protected mode checking, TCM checking and long-term behaviour checking.
According to the result, determine the OTN equipment between described any two different manufacturers, based on described OUTk interface, whether can realize interconnecting.
Respectively the possible implementation that business transmission checking, protected mode checking, TCM checking and long-term behaviour are verified is described in detail below.It should be noted that, the application does not limit to following described verification mode.
